Abstract: Embodiments include systems and methods for performing selection of a transport format combination by a device processor of a wireless communication device. The device processor may determine whether radio frequency self-jamming interference is detected at the receiver of the wireless communication device. The device processor may calculate an average transmit power reduction in response to determining that radio frequency self-jamming interference is detected at a receiver of the wireless communication device. The device processor may select a transport format combination based on the calculated average transmit power reduction, and may use the selected transport format combination to transmit data to a communication network.

Abstract: The present disclosure presents methods and apparatuses for enhanced received signal processing using signal-based channel impulse response (CIR) estimation. For example, according to an example method presented herein, a user equipment (UE) or a component therein may receive a signal corresponding to a transmitted signal sent by a network entity, wherein the transmitted signal comprises at least a data channel, estimate chip contents of the transmitted signal, based on the received signal including the data channel, to obtain estimated chip contents, and compute an estimated channel impulse response (CIR) based on at least the estimated chip contents. Based on this estimated CIR, the UE may thereafter reprogram a received signal reconstruction filter, perform interference cancellation procedures, and/or adjust one or more equalizer taps. By performing such functions, the UE may exhibit improved communication characteristics and enable a more robust user experience.

Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.

Abstract: Methods and systems improve performance of a wireless communication device supporting an active communication in a first network on a modem stack associated with a first subscriber identity module. The wireless communication device may detect that a control signal was received on the modem stack associated with the first SIM, identify a percentage of scheduled uplink feedback corresponding to the control signal received on the modem stack associated with the first SIM that will be transmitted on the first network, and determine whether determining whether the identified percentage is less than a threshold. If the identified percentage is that will be transmitted to the first network is less than the threshold, the wireless communication device may ignore operations instructed by the control signal received on the modem stack associated with the first SIM.

Abstract: Various embodiments for managing carrier transmissions after a tune-away on a wireless communication device may include determining whether a network has received transmissions from a first carrier of a first subscription after completion of the tune-away from the first subscription to a second subscription. In response to determining that the network has not received transmissions from the first carrier, the wireless communication device may determine whether a second carrier of the first subscription is transmitting to the network after completion of the tune-away. In response to determining that the second carrier is not transmitting to the network, the wireless communication device may route transmission from the first carrier to the second carrier.
